5.3.6 Electronic Gears
It is necessary to adjust the electric gear to convert from the command pulse sent from position unit to the travel
amount of electrical actuator.
See “LECSA Operation Manual (Simplified Edition)”,section 5.3.4 for the recommended values for electronic
gears for each actuator model.
Please configure the electronic gear values according to the customer application.

Ex.)
Travel amount per 1 command pulse (P=10μm)
Actuator lead (L = 6mm)
[PA05] = 100 (Initial value)
[PA06]=100×100×10×
=100×100×0.01
=100
[PA07]=6 (Actuator lead (L) [mm])
*In case position control mode, "Travel amount per 1 command pulse"P = 10[um]
*In case positioning mode, "Travel amount per 1 command pulse"P = 1[um]

*[PA05] = 100 (Initial value)
The initial value of 100 corresponds to the "Nomber of command input pulses per revolution" of 10000 [pulses/rev].
* [PA06] = [PA05]×100×P×
* [PA07] = Actuator lead (L) [mm]
